Taken from a Nuclear Engineering
Seminar:
MONTE CARLO OPTIMIZATION OF THE IN VIVO XRF MEASUREMENT OF LEAD IN
BONE
R.P. Gardner, Q. Ao, and S. Lee
This work has been sponsored by the National Institute of Environmental
Health Sciences of the National Institutes of Health. The primary purpose
of the work is to improve the minimum detectable concentration that is
possible with both the K and L XRF methods of in vivo lead measurement
in bone. This has been accomplished primarily through the use of a comprehensive
Monte Carlo program called CEARXRF developed by the authors for that purpose.
The general problem of lead accumulation and in vivo measurement is first
discussed. Then the Monte Carlo code CEARXRF is described, an error analysis
is performed with it, some techniques for minimizing errors including
the Monte Carlo - Library Least-Squares (MCLLS) approach are presented,
and a Monte Carlo code called CEARPPU for describing pulse pile-up distortion
is presented.
